Plant Management
more efficient, wireless-enabled work processes in both project and lifecycle operations.
Layered safety and security Safety needs to be approached from a refinery-wide perspective, incorporating layers of safety, such as a secure process design, Abnormal Situation Management, and physical security. Robust safety technology, with integrated fire and gas detection, lowers the cost of safety and reduces the risk of incidents (Fig. 4).
is especially useful during unexpected events at the refinery when notifications from events in the field can be received by both systems and a coordinated response can be launched. Digital video, again shared between the security and control systems, allows operations to be aware of any security breach and prepare to act appropriately. In smaller plants, operators can provide security monitoring during off-hours directly from the control system in the control room. Any event related to security or operations, including
process alarms, may also trigger digital video capture, using technology rather than people to initiate recording. Real-time tracking of assets and personnel throughout the facility will allow both operations and security to monitor movements from one zone to the next. Alarms can be triggered by motion, lack of motion, or on duress by using a duress button on the locator tag. This is especially useful during an incident or emergency, when all personnel can be mustered at various points around the plant. Mustering lists are generated automatically.

With the design and implementation of an integrated refinery security solution, security technology can be equal to that at sensitive military, governmental, and private facilities around the world. Using the same solution platform as the technology, the security and control consoles share the same alarming and access structures, sharing information about the facility. This
Consider the entire lifecycle Most owner/operators look to a lifecycle model with certain objectives in mind which include the ability to accelerate revenue while reducing costs and improve quality with the ability to also adhere to standards or other compliance metrics. The I-MAC approach provides a better return on new construction investments over their entire lifecycles. ■
